Genes affected

RHOT2 (HGNC:21169): (ras homolog family member T2) This gene encodes a member of the Rho family of GTPases. The encoded protein is localized to the outer mitochondrial membrane and plays a role in mitochondrial trafficking and fusion-fission dynamics. [provided by RefSeq, Nov 2011]

May 01, 2024

The c.142C>A (p.P48T) alteration is located in exon 3 (coding exon 3) of the RHOT2 gene. This alteration results from a C to A substitution at nucleotide position 142, causing the proline (P) at amino acid position 48 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
